Nature
To dream of nature denotes freedom, tranquility, restoration, and renewal. You are utilizing your instinctual nature.
Zero symbolises nothingness and emptiness. You are experiencing a void in your life. The symbol may also share the same significance as a circle and thus denotes infinity, eternity, completeness, absolute freedom and holiness. Alternatively, the dream forewarns that you are going around in circles and headed nowhere. Perhaps your actions have been counterproductive. It also represents timelessness and the super-conscious.
To see or dream that you are a lion tamer suggests that you are able to keep your aggression and strength in check.
